Introduced rodents are a major threat to the biodiversity of
islands around the world.

House mouse populations provide reservoirs for disease, as well
as competing with native mammals.

In 2009 a National Threat Abatement Plan to reduce the impacts
of exotic rodents on biodiversity on Australian offshore islands of
less than 100 000 hectares was approved.

This project aims to eradicate mice from Boullanger and Whitlock
Islands, which are home to endangered Dibblers and Grey-bellied
dunnarts.

The islands will be baited with 10 kg/ha Pest-off 120 rodent
bait after the Dibblers and two species of skink have been
temporarily removed.
